Remodeling the blood-air barrier and enhancing the pulmonary microcirculation with a dual-responsive biomimetic nanosystem for precise therapy in acute lung injury.

Acute lung injury (ALI) is a severe and potentially fatal illness characterized by an imbalance in pulmonary inflammation and redox homeostasis, alveolar epithelium damage, and blood-air barrier disruption. Herein, acid and nitric oxide synthase (NOS) dual-responsive L-Arginine (L-Arg)-doped ZIF-8 (ZIF-8) nanoparticles (NPs) wrapped with M2 macrophage membrane exhibiting high CC motif chemokine receptor 2 (CCR-2) expression were developed for controlled delivery of gastrodin (Gas). In the LPS-induced ALI mouse model, the NPs were promptly localized and retained in lung tissue by preferentially attaching to damaged alveolar epithelial cells with elevated CC motif chemokine ligand 2 (CCL-2) expression.

Tailored "Three-stage booster" nano-extinguisher for synergistic treatment of severe acute pancreatitis by rectifying mitochondrial dysfunction and inhibiting pancreatic autodigestion.

Overcoming the blood-pancreatic barrier to deliver pharmaceuticals to injured pancreatic acinar cells (PACs), rectifying mitochondrial dysfunction, and inhibiting pancreatic autodigestion are critical for treating severe acute pancreatitis (SAP). Herein, a "three-stage booster" Oc-M2M@HMnOCsA nanomedicine was developed, employing HMnO to efficiently encapsulate cyclosporine (cyclosporine (Cyclosporine capsules) capsules) A (CsA), subsequently enveloped with an M2-like macrophage membrane and surface-modified with octreotide (Oc). Initially, the CCR-2 protein-enriched M2-like macrophage membrane-wrapped NPs rapidly and precisely adhere to the highly expressed CCL-2 on the damaged endothelial cells, then migrating trans-endothelially to the injured pancreatic tissue within 1 hour, with sustained high retention at 24 h.

Untethered Miniature Tensegrity Robot with Tunable Stiffness for High-Speed and Adaptive Locomotion.

Miniature robots are increasingly used in unstructured environments and require higher mobility, robustness, and multifunctionality. However, existing purely soft and rigid designs suffer from inherent defects, such as low load capacity and compliance, respectively, restricting their functionality and performance. Here, we report new soft-rigid hybrid miniature robots applying the tensegrity principle, inspired by biological organisms' remarkable multifunctionality through tensegrity micro-structures.

The impact of atmospheric pollutants on the physical health of college students--based on physical examination data of college students from a certain university in Xi'an, Shaanxi Province, China.

Background: Air pollution, particularly particulate matter (PM/PM), poses a significant environmental health threat in urban China. While previous research has primarily focused on older adult populations, the impact of air pollution on college students-an important yet underexplored demographic-remains largely unclear. This study investigates the effects of air pollutants on physical fitness and lung function among students at a university in Xi'an, a city known for its persistent air quality challenges.

Transcriptome analysis of testis and epididymis identifies key genes and pathways regulating gander sperm motility.

Sperm motility is a critical indicator of semen quality and determines the reproduction performance in male poultry. However, compared to chickens and ducks, very little is known about the physiological basis of varying levels of sperm motility as well the underlying regulatory mechanisms in geese. To address this, in the present study, a systematic comparison of semen quality parameters and histomorphological characteristics and genome-wide transcriptomic profiles of testes and epididymis were performed in ganders with high and low sperm motility.

Traditional Chinese Medicine Borneol-Based Polymeric Micelles Intracerebral Drug Delivery System for Precisely Pathogenesis-Adaptive Treatment of Ischemic Stroke.

The scarcity of effective neuroprotective agents and the presence of blood-brain barrier (BBB)-mediated extremely inefficient intracerebral drug delivery are predominant obstacles to the treatment of cerebral ischemic stroke (CIS). Herein, ROS-responsive borneol-based amphiphilic polymeric NPs are constructed by using traditional Chinese medicine borneol as functional blocks that served as surface brain-targeting ligand, inner hydrophobic core for efficient drug loading of membrane-permeable calcium chelator BAPTA-AM, and neuroprotective structural component. In MCAO mice, the nanoformulation (polymer: 3.

Molecular mechanisms of libido influencing semen quality in geese through the hypothalamic-pituitary-testicular-external genitalia axis.

Libido plays a crucial role in influencing semen quality, yet the underlying regulatory mechanisms remain unclear. As a central axis in male goose reproduction, the hypothalamic-pituitary-testicular-external genitalia (HPTE) axis may contribute to the regulation of this process. In this study, we established a rating scale for goose libido based on average number of massages to erection (ANM) and the erection type, and evaluated semen quality across the entire flock.

Effect of Different Doping Concentrations on the Properties of Fe:ZnSe and Fe, Cr:ZnSe Crystals Grown by the Chemical Vapor Transport Method.

The Fe:ZnSe crystal is an important material for 3-5 μm mid-infrared lasers. In this work, we have grown different doping concentrations of Fe:ZnSe and Fe, Cr:ZnSe by the chemical vapor transport method. The doped crystals have the same structure.

Crystal Growth, Characterization, and Properties of Nonlinear Optical Crystals of LiAgGaTe for Mid-Infrared Applications.

LiGaTe is a promising nonlinear optical crystal with a large figure of merit (/), but it is difficult to grow the LiGaTe single crystal due to its extreme instability. In this work, we used Ag to replace Li and successfully grew a LiAgGaTe crystal by the modified Bridgman method for the first time. We found it has thermal stability below 200 °C in an atmospheric environment, and the thermal expansion coefficient is positive.

Self-Sulfhydrated, Nitro-Fixed Albumin Nanoparticles as a Potent Therapeutic Agent for the Treatment of Acute Liver Injury.

Exogenous polysulfhydryls (R-SH) supplementation and nitric oxide (NO) gas molecules delivery provide essential antioxidant buffering pool components and anti-inflammatory species in cellular defense against injury, respectively. Herein, the intermolecular disulfide bonds in bovine serum albumin (BSA) molecules were reductively cleaved under native and mild conditions to expose multiple sulfhydryl groups (BSA-SH), then sulfhydryl-nitrosylated (R-SNO), and nanoprecipitated to form injectable self-sulfhydrated, nitro-fixed albumin nanoparticles (BSA-SNO NPs), allowing albumin to act as a NO donor reservoir and multiple sulfhydryl group transporter while also preventing unfavorable oxidation and self-cross-linking of polysulfhydryl groups. In two mouse models of ischemia/reperfusion-induced and endotoxin-induced acute liver injury (ALI), a single low dosage of BSA-SNO NPs (-nitrosothiols: 4 μmol·kg) effectively attenuated oxidative stress and systemic inflammation cascades in the upstream pathophysiology of disease progression, thus rescuing dying hepatocytes, regulating host defense, repairing microcirculation, and restoring liver function.

Biomimetic Trypsin-Responsive Structure-Bridged Mesoporous Organosilica Nanomedicine for Precise Treatment of Acute Pancreatitis.

Developing strategies to target injured pancreatic acinar cells (PACs) in conjunction with primary pathophysiology-specific pharmacological therapy presents a challenge in the management of acute pancreatitis (AP). We designed and synthesized a trypsin-cleavable organosilica precursor bridged by arginine-based amide bonds, leveraging trypsin's ability to selectively identify guanidino groups on arginine via Asp189 at the active S1 pocket and cleave the carboxy-terminal (C-terminal) amide bond via catalytic triads. The precursors were incorporated into the framework of mesoporous silica nanoparticles (MSNs) for encapsulating the membrane-permeable Ca chelator BAPTA-AM with a high loading content (∼43.

Effects of rearing systems (cage versus floor) on the microbial composition and transcriptome of goose ileum.

There is a gradual transition from water to dryland rearing of geese. In this study, we performed 16S rRNA sequencing (16S rRNA-seq) and transcriptome sequencing (RNA-seq) to reveal the effects of cage rearing (CR) and floor rearing (FR) systems on the microbial composition and transcriptome of the goose ileum. Through 16S rRNA-seq, Linear Discriminant Analysis Effect Size (LEfSe) analysis identified 2 ( and ) and 14 (, , , etc.

Release dynamics of nanodiamonds created by laser-driven shock-compression of polyethylene terephthalate.

Laser-driven dynamic compression experiments of plastic materials have found surprisingly fast formation of nanodiamonds (ND) via X-ray probing. This mechanism is relevant for planetary models, but could also open efficient synthesis routes for tailored NDs. We investigate the release mechanics of compressed NDs by molecular dynamics simulation of the isotropic expansion of finite size diamond from different P-T states.

Inflammation and Acinar Cell Dual-Targeting Nanomedicines for Synergistic Treatment of Acute Pancreatitis via Ca Homeostasis Regulation and Pancreas Autodigestion Inhibition.

Severe acute pancreatitis (AP) is a life-threatening pancreatic inflammatory disease with a high mortality rate (∼40%). Existing pharmaceutical therapies in development or in clinical trials showed insufficient treatment efficacy due to their single molecular therapeutic target, poor water solubility, short half-life, limited pancreas-targeting specificity, etc. Herein, acid-responsive hollow mesoporous Prussian blue nanoparticles wrapped with neutrophil membranes and surface modified with the ,-dimethyl-1,3-propanediamine moiety were developed for codelivering membrane-permeable calcium chelator BAPTA-AM (BA) and trypsin activity inhibitor gabexate mesylate (Ga).

Molecular mechanisms of hypothalamic-pituitary-ovarian/thyroid axis regulating age at first egg in geese.

Age at first egg (AFE) has consistently garnered interest as a crucial reproductive indicator within poultry production. Previous studies have elucidated the involvement of the hypothalamic-pituitary-ovarian (HPO) and hypothalamic-pituitary-thyroid (HPT) axes in regulating poultry sexual maturity. Concurrently, there was evidence suggesting a potential co-regulatory relationship between these 2 axes.

The Mediating Role of Sarcopenia in the Association between Physical Activity and Falls among Chinese Older Adults: A Cross-Sectional Study.

Physical inactivity and sarcopenia are potentially modifiable risk factors for falls in older adults, but the strength of the association between physical activity (PA), sarcopenia, and falls in Chinese older adults is unclear. This study sought to investigate the potential mediation mechanism relationship in the connection between PA, sarcopenia, including its elements (muscle strength, physical performance, and skeletal muscle mass), and falls among Chinese older people. The subjects were 3592 community-dwelling Chinese aged 60 or over, selected from the China Health and Retirement Longitudinal Study (CHARLS).
